Short excerpt only, so you can decide whether to click out.
Hermes PayGuard is a standalone Hermes plugin for safe-by-design USDC and x402 payments.
It does not patch Hermes core. It installs as an add-on and gives Hermes payment tools with an explicit operator boundary:
PayGuard follows the same trust-boundary philosophy as CaMeL Guard, but adapted to payments.
